The game itself has been out for nearly three weeks now and has been mentioned on numerous websites. I am currently compiling a list of all of them and will post links to them in another post. As part of promoting the game we have posted the trailer on GameTrailers.com, with more gameplay videos to come.

After launching the game, a few dedicated members of the Vertigo Games forum noticed some bugs and improvements that could be made, so an update is currently in the works which will be submitted by the end of September. Expect to see that come in to effect during October.

Game update coming soon. Don't get too excited but it should fix up some of the smaller bugs.
At the moment, I am developing two new game concepts, one of which is with Vertigo Games. Both are platform games so I am working on a robust platform engine that can be re-used for both potential titles. In a couple of weeks I will have screens from one of them.
